Synthetic example 1
[0125] Synthesis Example 1: Synthesis of Pentaerythritol Tripropylene Glycol (A-1)
[0126] After adding 1.37 mol of pentaerythritol triallyl ether to a round flask, it heated at 40 degreeC. Then, 4.51 mol of acetic acid was added dropwise at a molar ratio to pentaerythritol triallyl ether of 1:3.3, and the mixed liquid was stirred at 40° C. for 4 hours. After adding 560 g of a 20% ammonia aqueous solution to the reactant, the reaction was carried out at 55°C for 15 hours. After separating the organic layer, 490 g of toluene and 350 g of 5% sulfuric acid were added and washed, and then the organic layer was separated and obtained, and 350 g of water was added to the organic layer.
[0127] The organic layer was separated, concentrated and dried, and pentaerythritol tripropylene glycol (478 g, yield 98%) (referred to as PEPT) was synthesized into a colorless and transparent oil. The results of NMR analysis are shown below.

Synthetic example 2
[0130] Synthesis Example 2: Synthesis of Dipentaerythritol Tetrapropanol (A-2)
[0131] Synthesis was carried out in the same manner as in Synthesis Example 1, except that dipentaerythritol tetraethyl ether was used instead of the pentaerythritol triallyl ether in Synthesis Example 1, and thioacetic acid was added dropwise at a molar ratio of 1:4.4.
Synthetic example 3
[0132] Synthesis Example 3: Synthesis of Pentaerythritol Tetrapropanol (A-3)
[0133] Synthesis was carried out in the same manner as in Synthesis Example 1, except that instead of the pentaerythritol triallyl ether of Synthesis Example 1, pentaerythritol triallyl ether was changed to pentaallyl ether and thioacetic acid was added dropwise at a molar ratio of 1:5.5.
